PROBLEM TO BE SOLVED: To provide a cultivation method using an ionic water generator for increasing yield of rice and improving the taste of the rice without restricting a fertilizer management to a conventional quantification and relying thereon.SOLUTION: According to the present invention, there is provided a method for increasing yield of brown rice and improving taste in rice cultivation. Here, with regard to the time of implementation, an implementation recommendation time and an implementation prohibition time are clearly differentiated according to a rice growth process. Agricultural water is used for cultivation immediately after being electrolyzed.SELECTED DRAWING: Figure 1【課題】 本発明は施肥管理を従来の定量に留め依拠することなくイネにおける収量増加と食味向上にイオン水生成装置を用いた栽培方法で提案する。【解決手段】 実施時期については、実施推奨時期及び実施禁止時期をイネの生長過程に応じて明確に区別し用水を電気分解したのち直ちに栽培に使用する。【選択図】図1
